Is a sonic boom heard by the passengers traveling in a supersonic aircraft? why or why not? a.) they do not experience any shift in frequency because they are traveling at the same speed as that of the sound source.
b.) they do not experience any shift because they are traveling at a lower speed than that of the sound source.
c.) they will experience a small shift in frequency because they are traveling at a lower speed than that of the sound source.
d.) they will experience a large shift in frequency because they are traveling at a greater speed than that of the sound source.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?
